When switching the no - load overhead lines by alternating - current high - voltage circuit breaker which is a kind of daily operations in electric power system, over - voltage is probably bringed out and insulating property of the electric devices is breakdowned sometimes, especially, when occuring re - strike. the main purposes that the tests on switching line - charging current are performed in the laboratory are assessing re - strike performance of circuit - breakers. according to the test results, the design of the circuit - breaker is optimized and re - strike performance is improved
交流高壓斷路器是電力系統中最關鍵最重要的設備之一,斷路器開合空載架空線路是電力系統中常見的操作,操作過程中通常會出現過電壓,對系統絕緣造成威脅,嚴重時會破壞系統的絕緣性能,發生事故,隨著電力系統電壓等級的提高、輸電線路不斷延長及傳輸容量的增大,由操作過電壓引起的絕緣閃絡、設備破壞事故的幾率更加突出。The fault diagnosis of the analog circuits is an advanced synthesis intercrossed subj ect, which is an application technology absorbing the new theory, technology and method in other subjects and fields. in the past 40 years, it has developed a great deal of theory and approaches. but the approaches are limited to deal with fault diagnosis because of the variety and complexity of the analog circuits, especially the large - scale analog circuits with the tolerance or the soft fault. artificial neural networks ( ann ) which have been one of the most active research areas recently can be contributed to solve problems in various practical fields. in this paper, analog circuit fault diagnosis approach based on pattern recognition, and ann is expatiated
模擬電路故障診斷是一門不斷發展中的綜合交叉性學科,是在不斷吸收其它學科和領域的新理論、新技術和新方法的基礎上向前發展的一門應用技術。雖然經過了四十多年的發展,也已經形成了一系列的診斷理論和方法,但由於模擬電路特別是有容差的大規模模擬電路故障的多樣性和復雜性,使得可用於診斷容差模擬電路的故障和大規模模擬電路軟故障的方法還十分有限。人工神經網路理論近年來取得了快速發展,已開始在各個研究領域廣泛應用。Because direct torque control requires very high performance of real - time, the popular microcomputer core dsp is used as controller in the design of hardware. its high speed of running is suitable for the experiment. in the main circuit, there is a highly integrated power element : ipm as inverter, which includes seven igbt, has high switch frequency and fault diagnosis function
在本控制系統的具體實現上,由於直接轉矩控制對實時性要求很高,因此在硬體方面,採用了目前比較流行的數字信號處理器( dsp )作為系統的控制器,其處理速度高的特點正好符合本實驗的需要:在主電路中,本系統使用了集成度高的功率器件:智能功率模塊( ipm ) ,作為逆變環節,其集成了七個igbt ,實現了高開關頻率逆變以及故障診斷的功能,從而使控制系統的體積大大縮小、控制更加靈活。Due to the direct torque control requires very high performance of real - time, the popular microcomputer core dsp is used as controller in the design of hardware. its high speed of running is suitable to the experiment. in the main circuit, there is a highly integrated power element : ipm as inverter, which includes seven igbt, has high switch frequency and fault diagnosis function

可以說是電網中樞紐,而實施斷路器重要作用的核心部件就是弧觸頭,如果在動態使用中由於觸頭的失效而不能有效開斷的話,斷路器就會整機爆炸,後果就是它所連接的整個電網處于癱瘓狀態,電網的輸變電電壓越高,波及的面積越大,所以有必要對觸頭的動態燒損和失效進行詳盡的分析,減少或避免實際使用過程中的燒損和失效,從而穩定整個電網。Boss is core of telecom enterprise business, its main function is : business design, business arrangement, network design, network configuration, network management, billing and account, rating and discounting, cu stomer service, customer management, finance, dicision surport, office auto mation, informa - tion intercourse etc. after the organization of chian railcom dalian branch, the number of customer increased day and day, the demand of customer became more and more complication, and crc develop many new server, the old bill system and manual transaction can not deal with dialy work, it is necessary to establish a set of orient - customer boss
業務運營支撐系統是電信企業業務的核心支撐,其主要功能如下:業務規劃、業務部署、網路規劃、網路配置、網路管理、計費、帳務管理、客戶服務、客戶管理、財務結算、客戶營業、決策支持、辦公自動化、內部信息交流等。鐵通大連分公司成立之後,由於客戶數量的不斷增多,客戶需求日趨復雜,加上鐵通自身新業務的不斷開發,原有的計費系統及人工處理流程已無法滿足日常工作中的要求,因此,建立一套面向客戶、以業務流程為中心的boss系統已迫在眉睫。Whereas if the contacts are in series with the alternating circuit, due to the passing zero property of voltage, we must evaluate the condition of contacts according to voltage value
但當觸頭接入交流電路中時,由於電壓有過零的特徵,所以要根據電壓有效值來判斷觸頭是打開還是閉合。In china, because of the foundation telecommunication the facilities is continuously sound with network, for the opening of electronic commerce the exhibition type descend the good foundation, article analyzed our country electronic commerce characteristics that develop, our country the e - commerce develop the problem of the inside ease, chinese e - commerce counter plan that develop
